Retired teacher Erich Martel wrote the following letter to the Washington Post in response to its article about the sky-high expulsion rates of charter schools:

 
DC Charter High Schools Quietly Transfer Far More Students Than They Expel

The District’s Office of the State Superintendent of Education enrollment audits and the D.C. Comprehensive Assessment System reports and graduation reports show that charter high schools take advantage of their freedom from responsibility for educating challenging students by quietly transferring many more students than they expel. This may also help explain why charter lobbyists are opposed to charters becoming neighborhood schools [Mark Schneider and Robert Cane, “Why charters shouldn’t be ‘neighborhood schools,’ ” Local Opinions, Dec. 30].

In its Jan. 6 article on expulsions, The Post described a mother withdrawing her daughter Elsie to avoid having an expulsion appear on Elsie’s record and, unsaid, on Thurgood Marshall Academy’s. This is the tip of the proverbial iceberg. Elsie’s ninth-grade class numbered 138; by April 2010 (18 months later), the 10th grade testing cohort was 87 (28 boys; 59 girls!). Sixty-three students graduated in June 2012, 46 percent of the original ninth-grade class. Fifty-seven of the 75 missing students were removed from Thurgood Marshall’s reponsibility by transfer — presumably to traditional public schools — it claimed a graduation rate of 78 percent, higher test scores and the acclaim of being “high-achieving.”

Between the October 2010 and 2011 enrollment audits, D.C. charter high schools’ ninth, 10th and 11th grade cohorts transferred more than 1,350 students, according to the Office of the State Superintendent of Education. It’s time for a serious investigation of this practice.
